IIRC the discussion ended with confirmation that (H)ANA were not scalers as originally thought, but that the scaling hardware was included on the GPU - it wasn't just a software scaling implementation.I thought the whole 360 has a dedicated scaler chip was debunked (ANA and HANA are just video output chips). The 360 uses the GPU (Lanczos Interpolation algorithm?) to upscale images.
Doesn't matter regards support for displays. Developers still need to target different rendering resolutions, unlike XB360 developers who can render whatever resolution (even 640p ) and have it output for TVs and monitors to use.Plus, I thought it has been confirmed that the PS3 has a horizontal scaler chip.
